LIFELINE® 6020410 Glufosinate-Ammonium Herbicide 2.5 gals is a non-selective, post-emergent herbicide that provides broad-spectrum weed control of some of the most challenging weeds,including glyphosate-resistant marestail, hairy fleabane, malva and filaree. Using a unique mode of action, LIFELINE inhibits glutamine production in the weeds which leads to a breakdown in photosynthesis. This makes LIFELINE an excellent choice when developing your overall weed resistance management strategy.
